GDM2 2.14.5 (stable), the "SuperNovaBlastThree" Release

The 2.14.5 release is a stable release of GDM that fixes a security related issue discovered in GDM 2.14.4 only. I recommend not using GDM 2.14.4. Refer to bug details mentioned below for more information.

2.14.5 stuff:

- Explicitely adjust the effective GID before running the child session program to avoid remaining with high privileges. Fixes bug #340347.
